To a/ZZ whom it may concern:

Be it known that I, HENRY G. FISKE, a citif zen of the United States ofAmerica, and a resident of the city of New York, county of New York, andState of New York, have invented certain new and useful Improvements inElastic Vehicle-Tires, of which the following is a specification.

My present invention relates to elastic tires Io for vehicles, andparticularly to the means for attaching such tires to the rim in whichthey are held, said rim being also attached to the felly of the wheel.

Additional features of invention relate to x5 the construction of thetire itself and to the method of attaching same to the rim.

In the accompanying drawings, Figure lis a transverse sectionalelevation of the tire, rim, felly, and attaching devices. Fig. l? is zoa View of the tire shown in Fig. l in dotted lines, the same showing therelative diameter of the tire before it is compressed into the rim. Fig.2 is a view in elevation, partly in section, of the tire, rim, and fellyof Fig. 1. Fig. 2'a is a view in dotted lines, similar to Fig. laillustrative of the. locking wires and clamps, as in Fig. 2, but beforecompression. Fig. 3 is a plan View of the lockingwires and clamps bywhich the tire is secured to the rim. 3o Fig. 4 is a view in elevation,partly in section, showing the tire-compressing apparatus after the tirehas been compressed into position; and Fig. 5 is a detailed view of oneof the radially-moving arms of the tire-compressing machine. Fig. 6 isan edge view of the locking-wires for securing the tire to the rim, theirst position beingv indicated in dotted lines Vand the final positionin full lines. Fig. 7, is a detailed plan view of one of the lock- 4oing clamps, partly in dotted lines. Fig. S is a View in elevation,partly in section, also showing one of the clamps and locking- `wires.Fig. 9 is a plan view, partly broken away, showing the apparatus forcompressing the tire upon the wheel.

l As indicated in the drawings, A is the felly of the wheel, to whichspokes are attached in any usual or convenient manner.

B is a metal rim, which is securely attached to the felly A and isformed with a channel to receive the tire C.

. The tire C is made solid and of elastic material, as rubber, and itslower portion, which is seated in the rim B, is covered with one or morelayers of fabric D d, said fabric being lapped inward and projectingradially out- `ward and incorporated in the body of thetire yusual wearand tear; but where employed for Y tractive purposes severe tensilestrains are exerted which tearthe rubber away from the fastenings, andslight cutsand other injuries are greatly extended unless checked by areinforcement Similar to that shown.

The tire C is attached to the rim and felly by clamps F, which areT-shaped, having a head extending transversely of the tire and embeddedtherein and an internally-screwthreaded shankf, extending outwardly fromthe tire and adapted to pass through suitable openings in the rim andinto the felly. Screwbolts f are passed through the exterior of thefelly into engagement with screw-threads in the Shanks F to'draw thesame downward and to clamp the tire firmly in position.`

The tire C may be made in straight lengths, the ends of which aresubsequently united by any suitable cement, or it (the tire) may be madein a continuous piece; but,- however constructed, it is made somewhatlarger than the rim B, -as indicated fin Figs. l, 2, and is compressedinto place, and thereby reduced in diameter and its resiliencyincreased. The

clampsF are each provided with ways for g three locking-wires, one kateach side and one in the middle, equidistant. Two Of the wireengagingparts of each clamp G G' may-be simplel apertures therethrough ornotches at its under side,while the third, H, is in the forni of atubular connector adapted to receive the ends ofthe wires. The wires I't' I are formed in sections, the ends of which are fitted into theconnectors H, and one end of each wire is attached thereto by pin h orother suitable means, and when the tire is made these ends are somedistance apart to allow for them coming together when the tire iscompressed into the rim. Each locking-wire is preferably made in severalsections, so that the amount of slip necessary to accommodate thecompression in the tire will be absorbed in the several spaces betweenthe ends of the wires.

The tire may be compressed in to the rim by any suitable apparatus, butIhave illustrated a form of machine adapted to the purpose. This isshown in Figs. 4, 5, 9, in which K is a base-plateformedWithradialslotsk. Anumber of arms L are arranged upon the plate K andprovided with ribs Z at their lower sides adapted to move in lthe slotsk, and each arm is provided with a bolt and nut M to hold it in positionupon the bed-plate K. At the inner end of each of thearmsLisadownwardlydepending wedge-block N. At the outer end of each ofthe arms L is a segmental clamp n. A screw-threaded spindle O is securedat the under side of the bed-plate K, and upon said spindle is avertically-moving block R, havinga conical openingp in its interior,said opening being adapted to receive the extremities of theWedge-blocks N. The block R is moved up and down with respect to thewedge-blocks N by means of a screw-threaded block or nut P upon thespindle O,upon which nut the block Ris carried. Suitable handles Q areattached to the nut P, so that it can be turned to raise and lower blockR.

1n operation the wheel, comprising the felly A, rim B, and suitablespokes and hub, is laid upon the bed-plate, and the tire O,u'hich isthen larger than the wheel, as indicated in Fig. 9, is placed exteriorthereto, the tread of the tire resting in the clamps N, which have beenseparated by lowering the block R. As the block R is moved upward theclamps are brought together and the tire is compressed into position inthe rim B. As this operation takes place the shanksf enter suitablesockets in the rim and felly, and when the tire has been compressed intoplace the free ends of the wires I t' l are at .the same time forcedfarther into the clamps II, so that when the bolts f are set up in theShanks f the said clamps will act to draw down the wires to some extent,slightly crimping them at points Where they are engaged by the clamps,and not only holding them from radial displacement, but also acting toprevent the said wires from moving longitudinally in the clamps, andthereby effectually preventing expansion and loosening of the tire.

Where, as previously, a tire has been made with a binding or lockingwire vulcanized in place and in a straight piece which is joined beforeor after being placed upon the Wheel, it usually happens that thecompression is localized and becomes intense at some points and almostnothing elsewhere about the tire. A particular feature of my inventionis to avoid uneven pressure upon the elastic tire as the result ofcompression, and this is secured largely by making the locking-wires insections, the ends of which move toward each other when the tire iscompressed together with the arrangement of locking clamps which holdthe wires equidistant and secure a large basis of support within thebody of the tire itself.

While I have described my invention in detail, various minormodifications and changes may be made in view of the foregoing withoutdeparting from the invention.

Having described my invention, what I claim isl. The combination with asolid tire of elastic material, of a plurality of sectionallocking-wires embedded therein and clamps engaging said wires alsoembedded in the tire, said clamps being formed with tubular connectorsfor uniting the ends of the sectional wires.

2. The combination with a solid tire of elastic material constructed oflarger diameter than the wheel to which it is to be fitted, ofcontractible locking-bands embedded in the tire, and locking-clampsengaging said bands and also embedded within the tire and having shanksextending therefrom for engagement with the rim of the wheel.

3. The combination with a solid tire of elastic material, of a pluralityof sectional locking-wires embedded therein, clamps engaging said wiresand also embedded in the tire, said clamps forming tubular connectorsfor uniting the sectional wires, one of the Wires being fastened in theclamp and the other one free to move eudwise therein.

4. The combination with a solid tire of elastic material, of a pluralityot' sectional locking-wires embedded therein, clamps engaging said Wiresand also embedded in the tire, said clamps being formed with tubularconnectors for uniting the ends of the sectional Wires and with partsadapted to engage the continuous portions of the locking-wires.

5. The combination with a compressible solid tire of elastic material,contractile locking-bands embedded within the tire, clamps engaging thelocking-wires and embedded in the tire and having shanks extendingtherefrom for engagement with the rim of the Wheel, said clamps beingadapted to crimp the locking-wires when in final position.

6. The combination with an elastic tire of solid material, locking-wiresembedded therein and being free to move longitudinally of the tire,clamps engaging the locking-wires and also embedded in the tire, andmeans for compressing the tire into place upon the wheel and therebyconnecting the ends of the locking-wires in the clamps.

IOO

7. The combination with the rim of a wheel, of a solid tire of elasticmaterial provided with locking-wires embedded therein but free to movelongitudinally within the tire when the same is reduced in diameter bycompression,

and clamps engaging said wires an'd also em' greater diameter than therim, sectional wires embedded in the tire, clamps adapted to engage thewires, shanks extending from the clamps into the rim, means forcompressing the tire into the rim and threading the wires throughY theclamps and draw-bolts for engaging and drawing down the Shanks when thetire has been compressed into the rim.
